Rolls-Royce, the manufacturer of supercars and airplane engines, has unveiled a new mobile nuclear-powered reactor — reminiscent of the one created by the Marvel superhero Iron Man — aiming to revolutionize clean energy solutions for both terrestrial and extraterrestrial applications.
This week, the British company introduced its Micro-Reactor Concept Model, emphasizing its zero-emission power capabilities. "Our advanced nuclear technologies support many global Net Zero targets, solving energy dependence across many industries," Rolls-Royce said in a statement accompanying a video of the design.

The micro-reactor, based on established nuclear technology, utilizes a compact and modular design capable of providing one to 10 megawatts of power. Each particle of uranium in its core is surrounded by multiple protective layers, enabling it to withstand extreme conditions.
Engineered to be factory-built and easily transportable, the reactor is designed for flexible deployment. Rolls-Royce says it is designed to be moved by rail, sea and even into space, making it a versatile power source for various applications.

The company detailed the micro-reactor on its website, explaining that while both micro-reactors and small modular reactors (SMR) use nuclear technology, they serve different purposes within the Rolls-Royce nuclear portfolio.
Rolls-Royce describes its prototype as having a high power density, capable of supporting a range of operational demands by providing power and heat output as required. The development of such a portable reactor could mark a new era in nuclear technology, with applications across multiple sectors, including defense, remote civil and industrial power and space exploration.
For military use, the micro-reactor is designed to provide robust, safe power for Main and Forward Operating Bases with minimal maintenance and training. It supports the defense sector's energy transition, enhances national security and has significant export potential, Rolls-Royce says.
For remote civil applications, it offers long-lasting, clean power for isolated microgrids and strategic locations like overseas territories and islands, reducing reliance on traditional power sources and easing the load on national infrastructures.

In industrial settings, the system ensures continuous, reliable power, supporting grid independence and co-generation of heat and electricity. Rolls-Royce says this will help high-demand sectors meet clean energy and net-zero commitments.
In space, the micro-reactor's power-dense design could make it ideal for planetary exploration and spacecraft propulsion. It provides continuous power for lunar bases and satellite movement, thus supporting scientific and technological advancements in orbit.
According to Rolls-Royce, the first operational small modular reactor (SMR) is expected to be operational by 2029, with the regulatory process anticipated to be completed later this year.
